As you can see, it's not the amount of memory I'm passing it. Can you guys look into this? I hope it's not my graphics driver issue because Nvidia would probably never fix it. This crash happens quite a bit, just need to play for awhile and then it happens. It doesn't matter how much RAM I pass it. 4GB, 8GB, etc.
